Cryptocell on nRF52840 USB dongle?

[manumonti]

Hi all,

I'm interested in the new nRF52840 USB dongle. Currently I'm working on adding some security functionalities to nRF52840 PDK.

Is nRF52840 USB dongle compatible with Cryptocell library? And what about OPTIGA TRUST X?

I cant find information about this issue.

Thank you in advance,

Manuel Montenegro

Hi,

 

You can find examples for the CC310 and the optiga trust x in SDK v15:

http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/cryptocell_example.html?cp=4_0_0_4_2_1_0

http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/ifx_optiga_ecdsa_simple_example.html?cp=4_0_0_4_2_1_1

 

Note that none of our kits include the optiga trust x IC, so you'll need to order a module, as specified in the above documentation.

 

Kind regards,

Håkon

Hello Håkon, thank you for your answer.

I just took a look to CryptoCell examples in the SDK, but I only found code and examples for PCA10056, and not for PCA10059 (USB dongle). Is the code compatible between both boards in this case? And in the other examples?

By the way, will I find more examples for PCA10059 in the next version of SDK v15? When will it be released?

The PCA10059 does not have a debugger, so it relies on using the DFU (over USB) to be programmed. If you are going to actively develop, I would recommend that you get a nRF52840-DK instead, as this one has a on-board debugger.

Code between the two are almost compatible, where the difference is the button and LED outputs.

 

The next version of the SDK will have more project for the PCA10059, but I cannot state which, as I do not know. If you contact your regional sales manager (RSM for short), you will get more information on upcoming releases. If you do not have the contacts of your RSM, send me a private/direct message with your location, and I'll point to to your RSM

 

Best regards,

Håkon

I do see that both the SWD/IO and the SWDCLK are wired in the USB and therefore the USB dongle should be programmable through a DK. Also, debug can be handle through the SWD/IO and SWDCLK and the segger modules. It is currently how my custom hardware is developed right now.
